Key Takeaways
- • Michael Burry, the "Big Short" investor, publicly warned that an SEC plan to tokenize stocks without company consent "needs to be stopped from going forward," characterizing the regulatory shift as a path toward a "Snow Crash cyber-punk future."
- • The SEC's proposed "innovation exemption" would permit two classes of tokenized stocks: company-authorized tokens and third-party tokenized tokens trading 24/7 on blockchain platforms, circumventing traditional market hours (9:30 a.m.–4 p.m. ET weekdays).
- • Third-party tokenized stocks would lack standard equity privileges including voting rights and dividend distributions, though they would provide immediate blockchain-backed proof of ownership—creating potential fragmentation in equity markets.
- • Citadel Securities, a major institutional trading firm, formally opposed the SEC plan in December 2025, signaling institutional pushback against the tokenization framework beyond retail investor concerns.
- • The regulatory exemption could facilitate stock trading on cryptocurrency platforms, fundamentally altering market structure and settlement mechanisms for publicly traded equities.
Summary
Michael Burry, the prominent investor known for his prescient 2008 financial crisis bet immortalized in "The Big Short," has escalated public criticism of an SEC initiative to permit tokenized stock trading on blockchain networks. In a statement published on his Substack newsletter *Cassandra Unchained* this week, Burry warned that the regulatory plan represents a structural risk warranting intervention, invoking dystopian language to underscore his concern: "We may be headed full-on to a Snow Crash cyber-punk future. This may be the point in time that needs to be stopped from going forward by some future being."
The SEC's proposal operates under an "innovation exemption" framework that would establish two distinct tokenized stock categories. The first permits companies to voluntarily tokenize their own securities or authorize third parties to do so. The second—and more contentious—category would allow third-party tokenization of publicly traded stocks without issuer consent. Unlike traditional equities, third-party tokenized stocks would trade continuously on blockchain-based platforms operating outside conventional market hours, potentially 24/7, compared to the current U.S. market structure of 9:30 a.m. to 4 p.m. ET on business days.
A critical distinction in the SEC proposal involves equity rights. Third-party tokenized stocks may not carry standard privileges inherent to traditional share ownership, including voting rights and dividend distributions. However, tokenized structures would provide immediate, blockchain-verified proof of ownership—an efficiency gain offset by functional limitations for equity holders.
The regulatory initiative has drawn institutional opposition beyond Burry's public commentary. Citadel Securities, one of the largest equity trading firms in the United States, formally submitted an opposition letter to the SEC in December 2025, signaling significant institutional concerns about market fragmentation and operational risks stemming from the tokenization framework. This dual-front criticism—from prominent macro investors and major trading infrastructure providers—reflects substantive disagreements about whether blockchain-based equity settlement improves market efficiency or introduces structural vulnerabilities to U.S. capital markets.
